t it may concern: it known thot i, WALTER E. Tiromnr, lllhiilln, in thecounty of Plymouth and e of Miessechusetts, have invented cernnd usefulIn 'oroveineuts in Lests, e specification.

pivoted in the iorcport on a transverse inn j and in the heelpnrt on asimilar pin g.

Kill s eh'eedv sta ted I nrefe to combine all t e reeturcs o myinvention in this one member 0 and have therefore provided at its .Liedge e slot or note 2 operat ng es e to cot-ch over a pin or kee er ityand at geted slot m through the side or. the lost for receiving a hoolr(not shown) by moons of which the plate, or combined hinge member andlocking device, 40, may he pulled or pushed to the right or left withinthe lost, Fig. 1, as :desired, and, cod crating with the ping, I haveprovided a s ot c, c, the pert e 0' said slot extending Very nearlyconcentric to the pivot g to permit said plate-to be shifted within thelast as steted.

For the purpose of retaining the member 0 in its shifted positione'ndpermitting the lost tobe quickly unlocked, l. prefer to provide an arm(1 extending backwordly from the plate 0 to the bottom of the spindlehole go, said arm being herein shown as carrying it spring for normallypressing the some lriotionally' against the last and adapted to springout over e projection q, as shown in Figs. 1 end 2, when the last is inlocked position, but capable of being quickly retracted from saidposition by the engagement of a lip 0 of a tool n when the letter isrotated in ,the spindle socket.

l'regerd it as new to provide a combined locloond-hinge member shiftablewithin the lest, and also I regard it as new to have a lock attached tothe two sections of the lost. It is also new to operate this look b amovement thereof towards the bottom 0 the parts hinged together.

Another important feature of my invention resides in securing ewedge-like action for binding the parts together.

In a co -pending application, Ser. {574,143 filed on a joint inventionby myself end another, we have explained the di'lliculty in properlylooking a hinged last together due to the shrink ego of the Wood, andhave therein provided one form of locking device for overcoming thisdifliculty. Accordingly, l have herein set "forth another means ofsecuring the same end, end for that purpose have made the locking devicewedge-she ed, by extending the surface-oi the slot c" w ich. bearsagainst the )inf not quite concentric to the'pin g, as W1 1 be clearlyevident from the drawings where the some is slightly exaggerated forcleerness of illustration, so that as a result, the farther to the leftthe plate 0 is )ushed within the last, the more tightly wi the fore-pertend heel-pert be wedged or locked into rigid, lengthened position;

portion a hole opposite en elon- "in I the specific construction shown;the

is slightly inclined relatively to the pivot 9 so that as the slottravels over the 1pm fin locking the last sections together, the atterare brought nearer together, the farther the late 0 is rotated and hencethe more firm y the sections are held together.

The slot e is provided so that when the plate 0 is rotated to unlock thelast, the lastparts will still be connected together so as not to fallapart, said slot allowing the sections to slide on one another, andpermitting the heel-part to swing forward. The last can not be collapseduntil the member 0 has been slightly rotated on the pin g to unlock the,last and bring the slot c into line with the pin f and substantiallyparallel with the direction of collapsing movement. for resisting thedownward pressure when the last is in use bottom up is provided byhaving the three pins wide y separated, the

in f being above the center .line of the last, it below the same and gnearer thereto so that strains brought upon the last tending to pull ors ring the last sections apart are resisted by t 1e pin 9 inthe heelsection and the pins f and It in the toe section, and said sections cannot slide on one another to shorten the last because the inclination ofthe slot e operates rather, when the last is locked, to draw thesections more tightly together. The

Wedge-surface of the inner side of the slot 6 crowds the heel pivot gand the pin f apart and hence binds the bottom secant surfaces slot ctighter, the separating ell'ort of pins 9 andf serv ng to pinch or drawtogether more tightly the bottom front wall oi the heel part and thebottom rear wall ol' the iorepart.

I do not coniine myscll to the spring for l'iolding'the parts, but mayuse any suitable means under condil ions ol' light use, or, when thelast is simply lel't in the shoe, it may be omitted and also the arm (1maybe left oll', the plate c being simply operated by the hook insertedthrough the side opening m.

.l have already sulliciently described the operation of my invention inconnection with the description ol its construction; it will be:

observed that the arrangement oi the slotted connection. and itssecuring devices is such that the slot permits the pinsf and (,1 toapproach each othcr as the last collapses As already iminm'led, one'l'eature o'l my hinged l'nst rcsidrs in providing mcans'w'hich permitsthe lasl to move l'roln its working position into its shortened position witlnnltliist lengthening, and (his rcsult is secured by'providingthe hinging connection or link that being the 'l'orm ol' hinge memberhcrcin shown) with ability to more in the last, the idea being lo haverelative movement of the heel-part with rclal ion to said link orhinging device, so as to bring i lie-parts into such rclative positionthat the heel-part may be moved into ils shortened position withoutlirsl Inormg rearwardly.

(.lreat strength.

It will be evident that, inasmuch as the two pivots f and g of theplate-hinge member or link a are not in horizontal 'ali'nement, but thepin f is nearer the top of the last, it would be impossible for the saidhinging device cto turn on the in f as a center Without swinging the.hee art rearwardly and thereby lengthening t e last before it shortens,but by having the hinge plate 0 swing at different times on the pins fand g and roviding relative movement between the lingo and last,thisdilliculty is obviated and the last is collapsed without firstlengthening.

, As already cx )lained, I prefer to have a sliding movement between thefore-part and heel-part, and for this reason have provided the lower orlonger portion 0 of the slot.

What I claim as my present invention and desire to secure by LettersPatent, is

1. A last, comprising two sections having opposed sliding faces, amovable latch pivotally secured in one of said sections and projectinginto the other section, said latch being formed with a slot, and a pinon theother section occupying said'slot.

2. A hinged last comprising twoseictions, a movable member pivotallysecured in one of said sections and projecting into the other section,said member being formed with a slot extending in the general directionof swinging movement of said member, and a pin on the other sectionoccupying said slot when the sections are locked.

3. A last comprising two sections having opposed sliding faces, amovable member pivoted to one of said sections and formed wit h a slothaving a pin-gi'iiding portion and a pin-locking portion, the fennelmovable into parallelism with said faces by rotation of said member, anda pin on the other section occupying said slot.

4. A hinged last, comprising two sections,

a latch pivotally connected to both sections,

and means coi'iperaling with said latch for locking said sectionsrigidly together in lengthened position.
